Hi Shoppers, Mama B here:
When shopping for "the diamond engagement ring", you have to pay attention to your girlfriend, finding the right diamond engagement ring depends on it.
Most guys don't have a clue about diamonds, why would you, this is hopefully, once in a life shopping.
Finding the stone is easy, finding the setting more challenging. What color, look at the jewellery she wears most often, is it yellow gold or white gold. If you need to ask, find a way to be vague, use a friend as a cover, pretend he bought something for his girl, this way discussion is started. Once you get color decided, then you want to know style. Single stone, stone with side stones, triple stones. What she wants in a diamond engagement ring is hard to know, if all else fails, ask one of her friends, one you can trust to keep a secret. You could also check to see if she likes flashy jewellery, or simple jewelry which may make your decision easier.
Above all enjoy this event, and I hope you get the reaction you want.
